Description

DEVICE FOR THE TREAT OF SPINE ENT Pathologies

OBJECT OF THE INVENTION

The present invention is directed to a device for treating disease in the spine and is in the field of systems used for instrumentation, fixation and spinal prosthesis.

The present invention comprises a set of parts such that allow one way posterobilateral percutaneous approach. Not a thought to use open surgery, although it could also be implemented with open surgery system.

BACKGROUND OF THE INVENTION

Currently there are devices or instrumentation systems for the spine. All these instrumentation systems have been created and designed to treat pathologies of the spine. Pathologies can have an origin:

• Traumatic (fractures, sprains, herniated discs).

• Congenital (type deformities scoliosis, kyphosis).

• Degenerative (when a vertebral segment is unable to maintain spinal stability, chronic degenerative changes originate in the joints of the vertebral segment resulting in what is called osteoarthritis of the spine. If the status column is not corrected just deforming .

• Infeccioso (discitis and spondylitis).

· Tumoral.

All these pathologies originate pain in the spine that is the most important cause of sick leave and disability in the Western world. The source of pain in most cases comes from the competent in- intervertebral disc, so they have developed a multitude of instruments and devices that try to correct the above problems to relieve pain.

Most of these systems which is intended to fix the diseased or damaged vertebral segment preventing movement of the disc space and thus relieves pain n- do dorsal cervical or lumbar spine. These fastening systems are in most cases with open surgery, exposing an area of ​​the spinal segment being treated.

Thus exposed openwork the anterior, lateral or posterior surface of the column and exposed once the device is placed. This is the case of the patent US4834757 publication number Brantigan or patent publication number US5015247 with Michelson.

Alongside these devices used to fix the vertebral segment, other devices have been invented, which always placed after open surgery, may allow some mobility of the vertebral segment. These devices are called intervertebral disc prosthesis. This is the case of Spanish patent with publication number ES2310255T3 and ES2177578T3. Placement in the human body of the devices can be performed by three different techniques: a) open surgery, which can be in different ways: above, anterolate- ral, posterolateral or later. Open surgery can be placed practice totali- ity of interbody disc prosthesis or fixatives (boxes, screws, plates, bars, etc.). To apply this type of surgery should expose the vertebrae face and the desired visual control device is placed. b) Minimally invasive surgery. It is an open surgery which uses incisions tions and exhibitions small, less aggressive. With this type of surgery also disc prostheses and intersomatic pedicle screws are placed posterior attachments. c) Percutaneous surgery. This technique not exposed directly disposed co or vertebrae. The position of the instruments inside the body is determined by x-ray is a closed surgery. Percutaneous surgery is achieved a needle into a vertebra or into the disc. Through the needle you can introduce a trocar and dilators and through the dilators can be placed screws and different devices.

Currently, percutaneous surgery can be placed posterior instrumentation transpedicular systems, screws are inserted into the vertebrae through a posterior approach the pedicles and then connected with vertical bars. They can be removed intervertebral discs (percutaneous discectomy), or perform other operations on the disc, (nucleoplasty radiofrequency etc.). They can also make punctures of the vertebrae to biopsy or introducing cement into the vertebra (vertebroplasty and kyphoplasty). So far, it is not known to have been placed prosthesis or fixation system Interbody per- cutaneous surgery, posterolateral route.

The device of the present invention is designed to be placed by percutaneous surgery, guided by x-ray, used ndo a new surgical technique, with appropriate instrumentation for placement, and would be included within the systems of vertebral interbody fixation using a satellite percutaneous and posterolateral approach. This involves stabilizing two vertebrae without having to make a direct exposure of the same. Currently there is no system with these features, which allow the operation to place a device that directly stabilize the bodies of two adjacent vertebrae percutaneously without open surgery.

This difference solves an important technical problem in the pathology of the intervertebral discs, since you can place the fixing device by percutaneous approach, only producing small incisions that are usually between 12 and 15 mm long on the skin of the patient.

DESCRIPTION OF THE INVENTION

The invention relates to a device for treating disease in the spine as instability between two or more vertebrae in the spine or a deterioration of the intervertebral disc, with these pathologies of congenital, traumatic, degenerative, infectious or tumoral .

The device comprises two bar-shaped elements which are inserted between the two vertebrae to be stabilized and are joined together to give rise to a stable attachment between vertebrae. This device, unlike the devices of prior art, allows the insertion piece by piece by percutaneous surgery and then allowed to be mounted inside percutaneous surgery also not open, in the intervertebral space. Thus the insertion method is performed with a skin, per- bilateral surgery to access the intervertebral space. That is, by surgical instruments access is given to the posterolateral disc or vertebra with an orientation directed toward the center of the disc without the need to make use of open surgery.

The first tool used is a cannulated trocar that can reach the center of the disc from both sides. Through cannulated trocar Kirschner wire that is made to reach the center of the intervertebral disc is passed. This needle guides in the following actions and on it are superimposed (following through its outer part) progressively larger dilators diameters up to place a stent of the appropriate diameter to the implant. The implant will be constituted by the rod-shaped elements which lead to the device of the invention and are to be placed between the vertebrae. Thus, once placed the two final dilators, one on each side, first disk is removed by known techniques and then proceeds to introduce, between the two vertebrae that are to stabilize the two elements shaped bar It comprising the invention through the dilators which now serve as guide.

The device therefore comprises a first shaped bar extending along a longitudinal axis and comprising at half end connection with a tool to allow the insertion and manipulation between vertebrae by percutaneous surgery.

Through one of the dilators first element is inserted into bar form. As one of its ends has linking means with the tool, using such a tool can push, pull and manipulate the rod-shaped element until its final position.

The rod-shaped configuration extending lengthwise is to allow the insertion between vertebrae through the dilator given the tubular configuration of the latter.

In the description of the embodiments of the invention specific modes of connection between the tool and the rod-shaped element is shown.

The invention also comprises a second shaped bar extending along a longitudinal axis and comprising at half end connection with a tool to allow the insertion and manipulation between vertebrae by percutaneous surgery.

As with the first rod-shaped element, this second element shaped rod is inserted through the other dilator is placed across the column by percutaneous surgery. The second rod-shaped also has engaging means with a tool that is what allows insertion and placement to the end position, the position which facilitates engagement and the final binding between bos am bar shaped elements.

In the embodiments different surface finishes are incorporated to facilitate insertion through a matching axial movement with the longitudinal axis of the rod-shaped, or by a rotating movement using an external thread which also facilitates entry or departure.

Finally, the invention comprises means for coupling between the first rod-shaped and the second rod-shaped such that once coupled together both elements their longitudinal axes at an angle such that it is possible to define a single plane parallel to either longitudinal axis. The device configuration according to the prior art or not sufficiently stabilize the relative position between the two vertebrae, and q ue percutaneous surgery as has been achieved is to place a screw or an insulated box give little stability; or it requires open surgery because the increased stability provides greater effective support area between vertebrae and said major area prevents insertion unless it is carried out by open surgery.

In the present invention, the use of two bar-shaped elements allows insertion percutaneous surgery; and reassembly inside so that an angle is maintained, to define a plane which, from a mechanical point of view means that the kinematics between the two vertebrae and the two elements in bar form is constituted by a system tico hiperestá- preventing relative movement between vertebrae even before the implementation of efforts between the two. This stabilization effect is higher when the first rod-shaped element and the second rod-shaped are coupled to form a near right angle.

It is distinguished between the terms coupling and connection as different relationships between the first and second rod-shaped element. The term link will be used to establish the link when maintaining two pieces have bearing surfaces designed to enter into contact r ta l so that the seat defines a stable position between the two parts. However, uncoupling is avoided if you have connecting means. The union is offered resistance or impediment to decouple. In the present invention the first and second elements are rod-shaped coupling means. Subsequent attachment set or because there are connecting means (eg a screw) or because after a period of ossification and generating fibers, the two parts coupled to form a single body.

The embodiments according to the dependent claims 2 to 11 set out particular embodiments of configuration of the bar shaped elements, of the linkages between them and other technical features that solve several partial technical problems. All objects of protection resulting from the different combinations of the dependent claims are incorporated by reference herein.

It is considered also incorporated by reference herein using a device according to any of claims 12 to 15.

It is considered ta m and either incorporated by reference herein method for treating a pathology column in a subject comprising implanting a device according to claims 1 to 12.

Technical advantages of the invention:

The device, by its design, remains fixed in the position in which it is intended to be placed. It is almost impossible migration thereof in the plane of the disc by the way that give two elements arranged converging in the connecting means, for example with a cross pattern, as would drag them all the structures, as well as system anchor in the bone. This positional stability makes no further complications requiring new interventions like other methods are expected.

With this new implant and applying percutaneous surgical technique without open surgery, all the complications of open surgery are avoided namely:

• No need to keep open a large incision for hours, thus avoiding infections.

• No need to make large incisions, so that bleeding is not abundant as in other techniques and does not require blood transfusion.

• No hematomas occur in the surgical bed after the incision sutured.

• No injuries to muscles and ligaments of the spine occur, not having to be cut to get exposure on the disc and vertebrae. Also not the structure of muscles and ligaments weaken, which are fundamental to the stability of the spine.

• No fibrosis and scarring in the vicinity of the nerve structures that in many cases are responsible for failed surgery of the spine in other open surgery techniques are formed.

In addition to the technical advantages, economically mportante means a reduction of costs for the healthcare system and the patient. When open surgery transpedicular fixation is used, or for placement of prostheses or interbody devices, the patient must remain in the hospital during prolonged periods (7 days or more). With this method the patient's stay in hospital is only 24 to 48 hours, thereby saving hospital stays for the care of that patient, the patient also gains time to carry out their normal life.

• It also has other benefits from the possibilities offered by the device, such as the absence of large scars, avoiding an aesthetic problem.

• The time the patient has to rest until the wounds heal completely and can make normal life is shorter and shorter sick leave.

• The surgery time is approximately one hour with what expense saving surgery, as any open surgery of this type generally requires more than 2 hours.

· Placing the system it can be done with sedation, as it can be done in an hour and is not overly painful. General anesthesia thereby intubation problems and complications of general anesthesia are avoided required.

• It is easier to remove the device, if necessary. With current techniques must reopen the patient while this system can be performed, also percutaneously dismounting device for placement reverse way, not being necessary either open surgery.

The present invention is a device for the treatment of pa- ogy spine. This device solves the problem of getting a device operatively provided in between two vertebrae and that can be inserted through percutaneous surgery. The device of the invention solves this problem since it allows the insertion of the elements forming the through guides and also allows subsequent coupling inside.

Figure 1 shows in perspective two vertebrae (V) between which there is a space (E) which is where the device (1) be provided after surgery. an embodiment comprising three elements (1.1, 1.2, 1.3) as bar joined together, which are insertable through an axial displacement shown in the same figure, and a joined result in an X or cross perpendicular arms.

Figure 2 shows in plan a vertebra (V) wherein the base (Vl) vertebral disc (not shown for clarity in the figure) that is located where it is the device (1) when implanted is distinguished. The implant is made by accessing through the pedicles (V.2), in a position and orientation posterolateral, as indicated by the axes shown in phantom. Both axes converge at a point inside space (E) where the intervertebral disc is located before being removed. In this same figure are identified in the vertebra (V) the transverse process (V.3), and blades (V.4) connecting n with a spinous pófisis (V.5). Similarly, the end of the sheets (V.4) and symmetrically arranged articular processes (V.7) are observed.

Continuing with Figure 2 by solid lines the position of the dilators (D) allowing insertion, percutaneous surgery, the components of the device (1) only schematically shown by rectangles shown. The position and orientation of the dilators (D) is extending through the axes shown in phantom.

The embodiment shown in Figure 1 and corresponds to is- burning Figure 2 comprises three elements (1.1, 1.2, 1.3) in bar form are nsertados in a particular order and then fixed together. It is in Figure 4 where the same embodiment of the device is shown in more detail and is the example which will be described first. First element is inserted in bar form in this embodiment is short. This element denominate the second element (1.2) bar-shaped. This second element (1.2) bar-shaped and the other elements (1.1, 1.3) as bar used in this embodiment are substantially square section. In the upper and lower surfaces, which in operating mode contact the vertebrae (V), a set of projections which lead to a longitudinal grooved (1.1.5, 1.2.5, 1.3.5) is shown. The grooved (1.1.5, 1.2.5,

1.3.5) longitudinal stabilizes each element (1.1, 1.2, 1.3) in bar form from the surface of the vertebra (V) with which it is in contact in a direction transverse to the element (1.1, 1.2, 1.3) in bar form. The use of such instruments tilling a complementary splined surface of the bone allows better insertion and guiding the position of each of the elements (1.1, 1.2, 1.3) in bar form during placement. After placement, the coincidence of two slotted into the vertebra (V) and the elements (1.1, 1.2, 1.3) as bar also stabilizes the position of the device (1).

Additionally, each of the elements (1.1, 1.2, 1.3) in bar form in this rea tion exam ple, has a lso ta nurado ra (1.1.6, 1.2.6,

1.3.6) transversal to intersect the longitudinal grooved (1.1.5, 1.2.5, 1.3.5) results in a set of rectangular projections. The height of each of these projections is made variable and faceting to improve bonding with the vertebra (V).

Once inserted the second element (1.2) bar-shaped, another element is introduced in bar form, which denominate first element (1.1) bar-shaped and which in this embodiment is coincident with the longest element. This first element (1.1) bar shaped in its central part a central bore (1.1.4) through which allows leaving the accessible end of the second element (1.2) bar shaped to the first element (1.1) bar-shaped . Through this bore (1.1.4) central through is possible to fix the first element (1.1) bar-shaped with the second element (1.2) bar-shaped for example by a screw clamped to stop the first element ( 1.1) as the rod against the second element (1.2) as bar it has engagement means with the tool which has allowed its insertion and manipulation. In this case the screw thread on a thread (1.2.2) into the second element (1.2) bar-shaped head until imprisons a seat located in the bore (1.1.4) central through (seat not shown in the figure). Thus the first element (1.1) bar-shaped is caught between the screw head and the second element (1.2) bar-shaped. The three elements (1.1, 1.2, 1.3) as bar employees have an internal thread (1.1.2, 1.2.2, 1.3.2).

This embodiment is not shown in the figure, the figure incorporates an element (1.3) as additional bar. The threaded inside (1.2.2) of the second element (1.2) bar-shaped in this case is also the means by which the manipulation tool for insertion allows traction to the element (1.2) bar-shaped. This is the solution used in all elements (1.1, 1.2, 1.3) in bar form. The additional presence of a crenellated (1.1.3, 1.2.3, 1.3.3) makes it possible to apply a herra- lie torque to facilitate certain maneuvers. In this particular case, the crenellated (1.1.3, 1.2.3, 1.3.3) of the elements (1.1, 1.2, 1.3) as bar and internal threads (1.1.2, 1.2.2, 1.3.2 ) form the engagement means with the tool that allows the insertion and manipulation of such elements during per- cutaneous surgery.

In this same embodiment, the I shown in Figure 4, is introduced finally a third element (1.3) as rra ba ta lso short. In the example shown in Figure 4, instead of attaching the first and the second element (1.1, 1.2) in bar form using a screw as described anteriormen- like, the screw ensnares the three elements (1.1, 1.2 1.3) in bar form. In this case, the screw is not shown graphically thread on the second element (1.2) bar-shaped (of short length), and leaves trapped the third element (1.3) bar shaped by passing ra through its cavity longitudinal inner (in this case shown with thread (1.3.2) but not the screw thread because the diameter of the thread (1.3.2) is greater than the internal screw). The screw also moves apri- I sioned the first element (1.1) bar shaped to traverse perforation (1.1.4) transverse centerline.

Both elements (1.1, 1.3) in bar form are pressed because the screw head is seated on the end of the third element (1.3) bar-shaped. Additionally, in this position it is accessible through the dilator (D).

The screw may be substituted for example by the third element (1.3) bar shaped when it, instead of having a square section, has a cylindrical section. In the embodiments of the invention shown in figures such as Figure 3, 5 and 6, the elements (1.1, 1.2, 1.3) in bar form have a cylindrical configuration with circular cross section and showing a thread (1.1.1, 1.2 1, 1.3.1) outside. This thread (1.3.1) outside facilitates insertion by rotation and therefore its function is to promote the progress during the insertion operation; and subsequent attachment to the vertebrae (V).

In turn, if there is an additional screw which is capable of threading into the internal thread (1.2.2) of the second element (1.2) bar-shaped, the first element (1.1) bar-shaped trapped in the end.

In any of these described embodiments, the first element (1.1) bar-shaped and the second element (1.2) bar-shaped end and also coupled together.

It is also possible that only remain coupled and bonding is performed by the healing and ossification. In this case stability was achieved after a longer period of time.

The fixing ossification is promoted when any of the elements (1.1, 1.2, 1.3) as bar has notches (1.1.7, 1.2.7, 1.3.7) communicating the interior cavity with the external surface. Through these perforations (1.1.7, 1.2.7, 1.3.7), the creation of fibers and bone make the internal cavity is filled and linked with the bone of the vertebrae (V) is n contact and they want to stabilize resulting in a stronger structural assembly. Therefore, the internal cavities shown in the elements (1.1, 1.2, 1.3) in bar form are optional and can be refilled by the ossification process or by screws (2) internal as shown in Figure 9 facilitating connection between elements (1.1, 1.2, 1.3) in bar form.

In all examples the elements (1.1, 1.2, 1.3) bar-shaped having a hollow interior extending along its entire length and having an internal thread (1.1.2, 1.2.2, 1.3.2); however, this internal space may extend only partially and not necessarily be threaded.
